Personally I feel like Polycub isn't far away and Polygon(Matic) itself has had a lot going on with it. From the introduction of EIP-1559 which burns a bit of the limited supply of Polygon on every transaction to a huge price correction brining it back down to what I consider a BUY level.
For those of you who don't know about DeFi and in particular CubDeFi here's a quick crash course.
DeFi stands for decentralized Finance. It's offering financial instruments without relying on banks, exchanges and brokerages which often take a fee in exchange for their services. By providing liquidity to a DeFi platform you help the platform be able to do swaps and other exchanges for this you get a part of the fees collected which often times is paid back to you in the form of the native token of that platform. In the case of CubDeFi this token is called CUB.
CubDeFi also runs on the Binance smart chain but has connections to various other blockchains via it's bridge. Which can be found her > LeoBridge on of the other connections it has is to HIVEs blockchain in the form of the LEO token which is a second layer token on the hive blockchain. This LEO token can be wrapped on to the Binance smartchain and is called bleo which can be used in the DeFi pools as well.
At some point "soon" personally I feel we have a good chance of seeing it happen some time this month Polycub will launch and with is has been mention of an airdrop to CUB token holders. However this cub needs to be active on the CubDeFi platform in Kingdoms or Farms in order to be counted. This most likely will become a daily snapshot and rewards for 60 days total in which roughly 0.15 Polycub will be rewarded for each CUB. (Now of course all of this is subject to change before release these are just numbers/speculation from what I've come into contact with so far)
CubFinance or CubDeFi has two many areas you'll focus in. Either fully automated and pay a recurring fee on earnings from the Kingdoms section where you can stake CUB, CAKE(pancake swap) and a number of other tokens which auto compound and buy more of the asset for a small fee (this avoids you manually doing it and paying those transaction fees)
or
In DeFi Farms which house CUB-BUSD, CUB-BNB, BLEO-BNB, DEC-BUSD and CAKEPOP-BUSD. These farms run a higher investment risk however they also pay out a higher APR. Do your own research on this and make the decision yourself before investing. I'd recommend checking out this explainer What is Impermanent loss
Having your cub in these areas of CubDeFi will mean yours will be counted towards the airdrop (again from what I've heard so far this is all subject to change)
The biggest update with Polygon happened two weeks ago which is just about when markets started to nose dive. This update was called EIP-1559 which is the same update that Ethereum underwent with a token burn on transactions. However the key takeaway difference between Polygon(matic) and Ethereum is that Ethereum still continues to produce fresh tokens on each mined block. However Polygon on the other hand does not. It's a fixed supply and that supply continues to drop with every transaction. While it's minimal over time it becomes it should in theory slowly drive up the price value instead of diluting it.
The best spot I've been able to find so far to watch the Polygon token burn is https://burn.polygon.technology/
and for Ethereum - https://watchtheburn.com/
From those numbers Polygon in two weeks has already burned 544,000 tokens of the total 10 billion tokens. It's expected to bur roughly 0.27% of the supply yearly which is yes minimal but it is something.
